SIP 7000 Series
 |
|
The name SIP is synonymous with highest technical precision in manufacturing
technology within the modern precision machine industry. SIP has always
defined the benchmark when it comes to guaranteeing ultra precision over
decades. SIP machining centers are in operation worldwide where quality and
precision cannot be compromised in any way.
The 7000 series has a horizontal spindle
unit and is available in 4- or 5-axis models.
Complex workpieces such as helicopter gear
box housings can be crafted with the highest
precision. A 300mm quill is available for
deep hole boring. Its positioning accuracy is
an incredible 3.0 μm.
By the way:
At SIP, tolerances are not ascertained by
soft, regional, Asian standards but are in
accordance with the strictest metric
ISO or VDI/DGQ standards. |

Applications
|
|
- Precision is a prerequisite for highest safetyin
the aviation industry. For this reason safetycritical
bore holes and surfaces must be
precisely machined to within a 1/1000 mm
(0,00004 inch). Special alloys that are hard
to machine, as well as titanium are being
increasingly used for these special parts and
it is exactly here that the unrivalled strengths
of SIP machining centers really pay off.
- Sports and racing cars demand not only
manufacturing precision when it comes to
the production of high performance engines,
but also for the complete powertrain and
chassis. SIP ultra precision centers fulfil the
highest precision requirements in light construction.
- In the precision machine industry every
component tolerance has an effect on
the achievable accuracy of the complete
machining system. It is for this reason that
the best machine engineers in the world
trust the ultra precision of SIP for the manufacture
of quality critical components.

Machine concept

- The machine frame, cast as one piece from
high grade cast iron (GGG80), guarantees
top stability and long term precision. Its
3-point support does not require a special
foundation and it will even maintain its
volumetricefficiency
rate on a slightly uneven
surface.
- Thanks to their V profile on one side, the
roller
guideways are completely friction free
and can only expand parallel to the other
relevant components and measuring systems
- therefore guaranteeing precision. The
precision-ground roller bearings ensure virtually
frictionless movement. (P < 3 Micron
bi-directional positioning VDI/DGQ or ISO
standard).
- Only top quality steel scales, produced
in house, are used in SIP machining centers.
This has the advantage that the unique
precision
of the machine, even with temperature
fluctuations of up to 1°C per hour and
4°C per day, can be guaranteed.
- At SIP, scraping is done by hand. Starting
with the machine base to the linear guideways
and ball screws, to the spindle heads
and axis. This method bestows all our
machining centers with perfect geometry
and long term precision.
